Climate change poses severe risks for businesses, which companies as well as governments need to understand in order to take appropriate steps tomanage those. This, however, represents a significant challenge as climate change risk assessment is itselfa complex, dynamic and geographically diverse process. A wide range of factors including the nature of production processes and value chains, the location of business sites as well as relationships and interdependencies with customers and suppliers play a role in determining if and how companies are impacted by climate risks.
This research explores the methodological challenges for a national-scale assessment of climate risks through the lens of the U KClimate Change Risk Assessment (UKCCRA) process and compares the approaches adopted in the first and second UKCCRA (2011, 2016), while also reflecting on international experiences elsewhere. A review of these issues is presented, drawing on a wide body of contemporary evidence from a rangeof sources including the research disciplines, grey literature and government policy. The studyreveals the methodological challenges and highlights six broad themes, namely scale, evidence base, adaptation responses, scope, interdependencies and public policy. The paper concludes by identifying suitable lessons for future national climate risk assessments, which should guide the next phase of research in preparation for UKCCRA3 and those of national-level risk assessments elsewhere.
